February 2026 monthly summary for Netcracker qubership integration work. Focused on stabilizing data flows, improving export/import reliability, and delivering user-facing filtering enhancements that drive faster analytics and decision making. Key features delivered: - Live Exchanges Filtering: Implemented robust filtering for live exchanges, enabling users to filter by conditions (less than, greater than) and specific session attributes, improving operational visibility and troubleshooting. - Idempotency export improvements (runtime catalog): Fixed the export logic to retrieve subchains based on trigger types and idempotency settings so the idempotency tab exports are complete and correct. - Idempotency subchain export completeness (library): Updated export queries to ensure subchains related to idempotency are exported alongside their parent chains, ensuring the idempotency tab reflects all relevant data. Major bugs fixed: - Service Import Failure: Fixed a unique constraint violation on the technical labels table that caused service imports to fail, stabilizing onboarding of new services. - Idempotency subchain export completeness (library): SQL update to include idempotency-related subchains with their parent chains, ensuring correct mapping in exports. Overall impact and accomplishments: - Improved data integrity and reliability of import/export workflows across catalogs, reducing runtime errors and manual intervention. - Higher confidence in idempotency data for analysis and decision making due to complete subchain exports. - Better developer experience with a clearer, filterable live-exchanges view. Technologies/skills demonstrated: - SQL query optimization and data export/import workflow improvements - Idempotency data modeling and trigger-based export logic - Repository collaboration across multiple modules - Change traceability via commit references
